Specific details for implementing the invention

[0024] Terms and words used in this specification and claims should not be interpreted as being limited to their ordinary or dictionary meanings, and should be interpreted in a meaning and concept consistent with the technical spirit of the invention, based on the principle that the inventor can appropriately define the concept of the terms to best describe his invention.

[0025] Therefore, the embodiments described in this specification and the configurations illustrated in the drawings are merely the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention; thus, it should be understood that various equivalents and modifications that can replace them may exist at the time of filing this application.

[0026] Hereinafter, a real-time personnel count (APC) and disaster evacuation route guidance system and method using a UWB communication device according to the present invention will be described with reference to the attached drawings.

[0027] First, the real-time personnel counting (APC) and disaster evacuation route guidance system using a UWB communication device according to the present invention is described. As shown in FIG. 1, the real-time personnel counting (APC) and disaster evacuation route guidance system using a UWB communication device includes a control server (100), APC equipment (200), an environment sensor module (300), and a user terminal (400).

[0028] The above control server (100) receives personnel entry / exit counting information from multiple APC (Auto People Counter) devices (200) installed in various buildings, such as general commercial buildings or construction site buildings, which count the number of people entering and exiting the building.

[0029] In particular, the control server (100) calculates a disaster evacuation route based on user location information through the APC equipment (200) and transmits the disaster evacuation route to the APC equipment (200).

[0030] As mentioned above, the APC equipment (200) can be installed at the entrance of various buildings or at the entrance of a store within a building to count the number of people entering and leaving the building or store, and through this process, the number of customers entering the building or store by date or time can be counted.

[0031] The above APC equipment (200) is installed at the entrance of a building or store and can calculate the number of people in the store by counting the number of people entering and exiting through entry and exit data.

[0032] The above APC equipment (200) recognizes moving objects within the camera's field of view and identifies people based on their overall size and movement.

[0033] That is, to measure the height and size of the above APC equipment (200) object, the depth within the counting area is calculated to identify the person.

[0034] The Singi APC equipment (200) normally identifies the number of occupants entering and exiting the workplace and environmental information collected and transmitted by the environment sensor module (300).

[0035] However, when a disaster occurs, the above APC equipment (200) and the UWB communication module (210) of the user terminal (400) determine the exact location of the occupants and the location of the fire through communication and then transmit it to the control server (100).

[0036] Meanwhile, the above APC equipment (200) receives the disaster evacuation route in the event of a disaster, displays it on the LCD panel (220) included in the equipment, and transmits the disaster evacuation route to the user terminal (400) via UWB communication so that it is displayed.

[0037] The aforementioned UWB communication technology (Ultra-wideband UWB) is a short-range wireless communication protocol that operates via radio waves at high frequencies. Characterized by highly precise spatial awareness and directionality, it operates to enable mobile devices to effectively perceive their surrounding environment.

[0038] Through UWB, various devices are intelligently connected, enabling a wide range of functions from secure remote payments to locating remote controls. Furthermore, because accurate navigation is possible over large areas, users can use a smartphone to find restaurants at an airport or locate a parked car.

[0039] The aforementioned UWB communication technology calculates the precise location of another device by transmitting a frequency signal and measuring the flight time it takes to travel back and forth. This allows for the determination of not only the device's direction but also its distance.

[0040] The above APC equipment (200) can determine the exact location of occupants and fires through UWB communication with the user terminal (400).

[0041] The above-mentioned environmental sensor module (300) is composed of various sensors such as a temperature sensor, a smoke sensor, or an oxygen sensor that can collect various environmental parameters capable of determining the state of the environment.

[0042] The above user terminal (400) is a terminal such as a mobile phone or tablet that is easy to move while being carried by the user, and is capable of communicating with the above control server (100), APC equipment (200), and environment sensor module (300).

[0043] Meanwhile, if a disaster such as a fire occurs in the area where the user is currently located, the user terminal (400) photographs the QR code installed at that location and transmits it to the control server (100).

[0044] The user terminal (400) can transmit the captured QR code to the control server (100) and then receive guidance on the disaster evacuation route from the control server (100).

[0045] That is, the above QR code contains current location information, so the user terminal (400) can receive a route to evacuate from the corresponding location by photographing the QR code and transmitting it to the control server (100).

[0046] At this time, it is preferable for the user terminal (400) to register in advance with the control server (100) when entering a dangerous area such as a construction site.

[0047] In addition, the user terminal (400) communicates directly with the APC equipment (200) and the environment sensor module (300), transmits user location information and fire occurrence location information to the APC equipment (200) and the environment sensor module (300), and then receives guidance on the disaster evacuation route.

[0048] At this time, the user terminal (400) can receive guidance on the disaster evacuation route through long-distance communication with the control server (100), and can receive guidance on the disaster evacuation route through short-distance communication with the PC equipment (200) and the environment sensor module (300).

[0049] Meanwhile, the PC equipment (200) and the user terminal (400) each include a UWB communication module (210, 410) to transmit and receive the QR code or disaster evacuation route via UWB (Ultra Wide Band) communication.

[0050] A guidance method using a real-time person count (APC) and a disaster evacuation route guidance system utilizing a UWB communication device according to the present invention having the configuration described above will be explained.

[0051] The above APC equipment (200) performs the step of counting personnel at the installed site and obtaining environmental information (S100).

[0052] In the above S100 step, the APC equipment (200) counts the number of people entering and exiting using a camera inside the equipment equipped with an artificial intelligence model that has been pre-trained through AI learning.

[0053] The above environmental information corresponds to parameter information such as temperature, smoke, or oxygen measured by the environmental sensor module (300) installed at various locations on the site.

[0054] Afterwards, the above APC equipment (200) performs a step of determining in real time whether a disaster has occurred at the site while acquiring personnel count information and environmental information (S200).

[0055] In the above S200 step, the APC equipment (200) determines whether a disaster has occurred by comparing the environmental information transmitted from the environmental sensor module (300) with a threshold value.

[0056] That is, the above APC equipment (200) determines that a disaster (fire) has occurred when the parameters corresponding to temperature, smoke, or oxygen, measured by the above environment sensor module (300), are within the range corresponding to the occurrence of a fire.

[0057] In the event that a disaster occurs in the above S200 step, the APC equipment (200) performs the step of providing a disaster evacuation route to the user terminal (400) (S300).

[0058] The above APC equipment (200) performs a step of determining whether it has received an evacuation completion signal from the user terminal (400) (S400).

[0059] The above APC equipment (200) terminates the disaster evacuation route guidance system when it receives an evacuation completion signal, and if it does not receive an evacuation completion signal, it repeatedly performs the above S300 step of providing a disaster evacuation route while waiting for the evacuation completion signal to be received for a predetermined time.

[0060] At this time, when the above S300 step is repeated, it is desirable to provide the disaster evacuation route by updating it to the shortest distance based on the user's real-time location.

[0061] If no disaster occurs in the above S200 step, the above APC equipment (200) performs the step of providing only personnel count information to the LCD panel (220) (S300').

[0062] Step S300, which provides a disaster evacuation route to the above-mentioned user terminal (400), will be explained in more detail with reference to FIG. 3.

[0063] In the event that a disaster occurs in the above S200 step, the APC equipment (200) performs the step of obtaining user location information through communication between the internal UWB communication module (210) and the UWB communication module (410) of the user terminal (400) (S310).

[0064] The above APC equipment (200) performs the step of storing personnel count information and user location information and transmitting them to the above control server (100) (S320).

[0065] If no disaster occurs in the above S200 step, the above APC equipment (200) performs the step of storing only personnel count information in the above S400 and transmitting it to the above control server (100).

[0066] The above control server (100) performs a step of determining whether it has received user location information (S330).

[0067] The above control server (100) normally receives only personnel count information, but in the event of a disaster such as a fire, it also receives user location information. Therefore, it can determine whether a disaster has occurred based on whether user location information is received, and thus perform the above S330 step.

[0068] In the above S330 step, the control server (100) may determine whether it has received QR code information from the user terminal (400).

[0069] When the above control server (100) receives user location information or QR code information, it performs the step of generating a disaster evacuation route based on the user location information (S340).

[0070] In the above S340 step, it is desirable for the control server (100) to generate the disaster evacuation route using the shortest path, i.e., the shortest distance, from the user's location to the exit.

[0071] The control server (100) performs the step of transmitting the disaster evacuation route generated in step S340 to the APC equipment (200) (S350).

[0072] At this time, the control server (100) may transmit the disaster evacuation route to the APC equipment (200), but may also transmit it directly to the user terminal (400) that sent the QR code information.

[0073] The above APC equipment (200) performs the step of providing the disaster evacuation route received in step S350 to the user terminal (400) (S360).

[0074] In the above S330 step, if the control server (100) has not received user location information or QR code information, it performs the above S300, which displays personnel count information.

[0075] If no disaster occurs in the above S200 step, the above APC equipment (200) performs the step of providing only personnel count information to the LCD panel (220) (S300').

[0076] The step S300, which provides personnel counting information to the user terminal (400), will be explained in more detail with reference to FIG. 4.

[0077] The above APC equipment (200) performs the step of counting personnel entering and exiting the site (S310').

[0078] The above APC equipment (200) performs the step of counting personnel entering and exiting the site in step S310 and transmitting the personnel count information obtained to the control server (100) (S320).

[0079] The above control server (100) receives personnel count information and performs the step of calculating personnel count data (S330).

[0080] In the above S330 step, the control server (100) calculates personnel count data by subtracting the number of outgoing personnel from the number of incoming personnel in single mode to calculate the remaining personnel, and calculates personnel count data by subtracting the total number of outgoing personnel per equipment from the total number of incoming personnel per equipment in group mode to calculate the remaining personnel.

[0081] For example, if three people are required to operate an excavator on-site, the number of personnel entering the site becomes three when the excavator is deployed, and conversely, the number of personnel leaving the site becomes three.

[0082] The above control server (100) performs the step of transmitting the calculated personnel count data to the above APC equipment (200) (S340).

[0083] The above APC equipment (200) performs the step of receiving personnel count data calculated and transmitted by the control server (100) and displaying it on the LCD panel (220) (S350').

[0084] Although the technical concept of the present invention has been described above together with the accompanying drawings, this is merely an illustrative explanation of preferred embodiments of the present invention and is not intended to limit the invention. Furthermore, it is evident that anyone with ordinary knowledge in the technical field to which the present invention pertains can make various modifications and imitations within the scope of the technical concept of the present invention without departing from its scope.
